The RK84 is a 75% mechanical keyboard with tri-mode connectivity (Bluetooth 5.0, 2.4GHz dongle, wired USB-C) and a hot‑swappable PCB plus a ~3750mAh battery. It’s a feature-rich compact board for mixed wireless/wired use with customizable RGB and RK Gaming software, but expect Windows‑only software, occasional firmware/software quirks, and limited dongle range in 2.4GHz mode.
Buy if you want a compact 75% with hot‑swappable switches, tri‑mode wireless, and deep Windows customization; avoid if you need macOS software support or rock‑solid 2.4GHz dongle range.
